strip secured to the side wall and then told-edl outwardly and downwardly around the en posed edge of the base. This was, necessarily, a manual operation and theref'oreu the cost of manufacturing boxes formed in this manner was high. Later, as shown in reissue Letters Patent Nos. 17,183 and 17,828 issued to me on January l, 1929, and dune 18, 1929, respectively, there was made a box Voi? this type which could be made on a machine because the side wall was attached to the bottorn and then the base was attached to the" bottom by means other than the attaching means for the side wall. However, no boX has yet been devised which can be manufactured on a machine and in which the side wall is attached directly to the base.

`ilse, heretofore glue has been relied upon entirely in securing the various parts of the boX to one another and when boxes are man-r ufactured rapidly in large quantities trouble has been encountered in arovidino' sufficient pref-sure upon the parts glued to malre the glue stick to the extent necessary to form 'a strong box.

The objects of my invention are to provide a box of the class described in which the side wall is secured tov the base and to provide a box in which the parts are secured to one another in such away that glue is not wholly relied upon to maintain adjusted position.

A heart shaped box embodying my invention is shown in the accompanying drawing the parts in wherein similar characters are used to desi nate similar parts and, although, for the saire of convenience and clarity l have shown only half of a box it is to be understood that a complete boi; consists of two such halves arranged with the side walls thereof slidablyy fitted one within the other: is a plan `view of the Ybox part and F ig.. 2 is a section Valong' the lines2-2 in Fig.` 1'.

Referring to the igures the embodiment of my invention shown therein comprises p af* base A, and a side wall B. The base A has the edge thereof curved in a heart shape and thevside wall B follows the contourV of the base,v as shown inFig; l. ProjectingV outwardly from and preferably at'substantiallyl: vright angles to theside wall B is a flange C Y which yis prefer-ably an integral part of the wall. f `The ange may be notched as-at D to allow the side wall to be bent in the desired shape to follow Vthe contour o' the base. The. sidewall is preferably-formed of one strip and one end of the strip may have an overlapping part Vlll arranged to extend over the other endwhereby the ends of the side wall are secured together in; the 'inshed 4boni',

.Breierablyi the liange `D terminates short of the overlapping part E.

`rllieniarginal. portionh` of the base A eX- tends outwardly past the side wall B along Aand beyond the outer edge of the iiange and is reversed over the edge of the flange and crimped thereon as at Gf. Paper or card- -boai'd of the weight commonlyl used can be zcrimped.intheinanner shown, but some cardboards cannot be stretched to the extent re- Voiuired in the crimping operations and, thereforeT it may he necessary that the reversed 'part Gr of the base likewise bel notched as at D. so that a firm-contact may be had when -it is crimped over the edge of the llange C." `lfilso, so that the bo'X will be as strong as possible llpreferthat any lnotches 1D in will not register', but'will lie' between one another as shownin Fig. l. In forming a heart shape boXthe notches D and D at the point aand the recess Z) are necessarily some-V what larger than the notches provided on the circumference of the sides.

It'should be noted that'in the figures the n'otches D are closest together where the currature fo the sidewall Bis greatest and are r' spaced further apart where the side wall Bl ythe reversed part G of the base are posi- Y tioned in'respect to the notches `D in the 4flange C so that the notchesin the two parts ico is more nearly straight. Likewise, if it is necessary to have the notches D inthe reof said base being likewise notched to allow a firm contact thereof with said ange and versed part vGr these notches will also be the notches in said flange being positioned closest together whererthe wall B is curved the most. n

In forming a box as described herein a relative to the notches in said reversed portion so as not to register therewith.

In witness whereof I have signed my name small amount of glue may be included beto the foregoing specification.

tween the contacting surfaces of the.V flange C and the marginal portion F of the base A and the reversed part Gr, but it may readily be seen that if the 'parts are formed asl described above the crimping of the marginal Y portion of the base over'the flange will hold the parts of the boX` in predetermined fixed relation and a rugged structure will be obtained. i

Y While I have shown a heart `shaped box in the drawing and described sucha box above it may be understood that boxes embodying my invention may be made in various sizes and' shapes without deviatilng from the spirit of my'inventionas included in the claims set forthy below.
